View or modify the existing passwords for transfers and user levels. Save the file and use it to update your panel. Option B: The "Password Hint" Check
Power cycle the HMI. During startup, press and hold the top-left corner, or tap opposite corners sequentially (depending on the specific GP model) to enter the boot menu.
If the HMI offline mode is locked but you need to pull the project file to modify it, you can bypass the network transfer screen using external storage.
ProFace units run a proprietary real-time operating system (RTOS). Security data is stored in:
Confirm the initialization to clear the connection key and internal settings. Unlocking Transfer Passwords (GP-Pro EX) proface hmi password unlock
Pro-face HMIs are known for robust security, but their lockout procedures are designed more for equipment protection than high-level encryption, which can be frustrating for maintenance.

This process completely wipes the runtime application, user logs, and recipes. The HMI will return to an empty, factory-fresh state, allowing you to download a brand-new project without a password roadblock. 5. Third-Party HMI Unlocking Tools: Risks and Warnings
If you need help finding specific settings for your system, let me know: View or modify the existing passwords for transfers
Older GP-Pro PBIII and early GP-Pro EX projects allowed developers to set password hints. When prompted for a password during an upload, look closely at the dialogue box for any developer notes or structural hints that might trigger memory recovery. 3. Technical Bypass: Forcing a Clean Factory Reset
A: Unlikely. Proface encrypts the password database. Without the official software or a bootable USB created by the official software, you cannot recover the password. You must purchase (or demo) GP-Pro EX.
Prevents unauthorized users from uploading or downloading the project file ( .prx or .obj ) from the panel.
| Practice | Implementation | |----------|----------------| | | Store all ProFace passwords in an encrypted vault (e.g., Bitwarden, Keepass) accessible to at least two maintenance engineers. | | Password-Protected Backup | In GP-Pro EX, use Project -> Security -> Create Backup File with Password Recovery Token . Save the .RBA file offsite. | | Hardware Key Storage | For SP5000 series, enable "Hardware Security Key" option; the password is stored on a USB dongle, not in the HMI. | | Annual Access Test | Verify that at least one password (Level 15) is known and functional by performing a test logout/login every 6 months. | During startup, press and hold the top-left corner,
Proface HMIs use standard flash memory chips (Winbond, Spansion). Using a (like a Segger J-Link or FT2232H):

When the Transfer password is unknown AND the Offline Mode is locked, you need hardware. Proface HMIs that support external storage (USB drives or SD cards) offer a backdoor via the .
